Hi , one more question. Can you add aroma therapy to the oxygen ionizer?
Hello Frank, I just checked an ionizer and there is not a chamber to add something like scent beads. In a sauna this size though, any aromatherapy you add would surely fill the air. You might consider one of these sauna scents: http://www.saunasandstuff.com/traditional-saunas/more-sauna-options/sauna-scents.html
